The Aprilia RS4 125 is a sporty, lightweight motorcycle that was produced by the Italian manufacturer Aprilia from 2011 to 2014. Designed to be an entry-level sportbike, the RS4 125 targeted young riders seeking an exhilarating experience while complying with licensing regulations for smaller displacement motorcycles. It boasted a sharp, aggressive design reminiscent of its larger, more powerful siblings, featuring a full fairing, a low-slung profile, and a distinctive twin-headlight setup. The compact dimensions and relatively low seat height made the RS4 125 accessible to riders of various sizes, while the lightweight construction provided agile handling and effortless maneuverability.

Under the sleek bodywork, the RS4 125 housed a liquid-cooled, 4-stroke, single-cylinder engine with a displacement of 125cc. This engine was known for its responsive throttle and smooth power delivery, making it enjoyable for both everyday commutes and spirited rides on winding roads. The RS4 125 came equipped with a 6-speed gearbox and chain drive, ensuring efficient power transmission and allowing the rider to find the perfect gear for any situation. The bike's suspension consisted of a telescopic fork at the front and a monoshock at the rear, contributing to a comfortable ride and predictable handling. The braking system utilized a single disc brake at the front and a single disc brake at the rear, providing adequate stopping power for the RS4 125's performance capabilities.
